- Products > HutlinerPacker® + Accessories
Special devices for placing Hutliner®, hat seals or short liners. HutlinerPacker® are combination devices which can be used optionally with or without rubber hats. If you remove the rubber hat, a short liner can be inserted. If the rubber hat is screwed on, either the hat seal alone is used or as a combination of short liner plus hat seal = Hutliner®.
The mobile HutlinerPacker® are not equipped with their own drive. To move them to a repair point, they are coupled to the robot system Talpa or comparable systems. The operator moves the HutlinerPacker® to the desired point and aligns it. Once the HutlinerPacker® is positioned in the sewer, the robot can be removed.
The pipe sealing cushion, also called straight bubble, works similarly to a short liner packer. It can be used to install short liners even in the joining area of a connecting line. This means that the installation depth of the hat seal can be extended.
